Question
Indicate whether each of the following statements is true or false. The oxygen pressure in capillary blood flowing to alveoli is greater than the oxygen pressure in alveoli. 1. 2. The oxygen pressure in capillary blood flowing away from alveoli is greater than the oxygen pressure in the body tissue. 3. The carbon dioxide pressure in alveoli is greater than the carbon dioxide pressure in capillary blood flowing to alveoli. Prior to reaching alveoli, the majority of hemoglobin in deoxygenated blood in veins is deoxyhemoglobin. 4. Oxygenated blood in arteries unloads the majority of its oxygen into body tissues prior to returning to the heart and lungs through veins. 5.Explanation / Answer
First of all we need to know that gases always flow from high partial pressure to low partial pressure.
1) F 2) T. 3)F. 4)F. 5)F
Only 25 percent oxygen is deliver to tissue and 75 percent remain in deoxygenated blood.
